IMPROVEMENT IN REVERSIBLE PLOWS.

Specificationforming part of Letters Patent No. 168,157, dated September28, 1875; application filed August 21, 1875.

To all whom it may concern:

Be it known that I, MYRoN R. HUBRELL, of Wolcott, in 'the county ofLamoille and State of Vermont, have invented a new and usefulImprovement in Reversible Plow, of which the following is aspecification:

Figure 1 is a bottomview of my improved Fig. 2 is a 'rear view of thesame. v

Similar letters of reference indicatel corresponding parts.

The object of this invention is to furnish an improved reversible plowwhich shall be so Vconstructed that the point of draft attachment may bechanged from one side of the beam tothe other Vby the operationofturning the mold-board from one side to the other.

The' invention consists in the rod running lengthwise with, and swiveledto, the beam, connectingat its rear end with the reversible mold-boardby the slotted tube and hooked rod, or equivalent device, and'at itsforward end with the draft-hook or a clevis, as herein-V afterfullydescribed.

A is the plow-beam, to the rear end of which the handles B lareattached, in -the'ordinary manner. G is the foot, land-side, andstandard, which is rigidly attached to the rear part of the beam A. D isthemold-board, which is pivoted tothe front and rear ends of the foot Cby means of brackets, so that it may be turned from one side to theother of said beam. To the rear end of the mold-board D is pivoted atube or socket,'E, lwhich is slotted upon its rear side from its outerend nearly to its inner end, and through which passes a i rod, F. Therod Fhas a hook formed upon each end, the hook upon the outer end'serving as a catch to keep the rod- F from being drawn longitudinallythrough the tube E, and which, when the rod F is turned one-quarteraround, comes into linewith the slot in the tube E, and allows the rod Fto be drawn 1ongitudinally through the tube E, the said hook passingthrough the said slot. The hook upon the inner end ofthe rod F passesthrough and is swiveled in a T- socket formed upon the rear end of therod G, which passes along the under side of the beam A, or through agroove formed in the under side of said beam, and is swiveled to it bymeans of keepers or bearings. Upon the forward end of the rod G isformed a hookz H, to which the draft is attached, and the point of whichenters alternately notches formed upon the opposite sides 0f the forwardend of the beam A, or of a metallic cap attached to said beam. Insteadof the hook H, a crank may be formed upon the forward end of the rod'G,and connected with a clevis' attached to the forward end of the beam A.By this construction, as the mold-board D is turned from the one side tothe other of the beam A, the point ot' draft ,attachment will also bechanged from one side .ent-

The combination of the draft-rod G, running lengthwise with, andswiveled to, the beam A, with the hooked rod F and the slotted tube E,connected with the reversible mold-board D, the rod Gr connecting at itsforward end with the draft-hook H or a clevis, substantially as hereinshown and described.
